Podisus maculiventris, the spined soldier bug, is a medium-sized predatory shield bug common in North America. It has prominent spines on each "shoulder" and preys on a wide variety of arthropods, particularly the larval forms of Lepidoptera and Coleoptera. As a generalist predator of many agricultural pests, P. maculiventris is generally considered a beneficial insect in gardens and crop fields.
The coloration of P. maculiventris ranges from pale brown to tan. The body is shield-shaped with prominent, well-defined "shoulders." A distinguishing feature is the presence of a black streak on the wing membrane, along with spined humeri, which serve as key diagnostic characteristics.
Adults and nymphs can be observed sucking and feeding on prey using their tubular mouthparts, which they can extend forward in front of the body. This differs from plant-feeding stink bugs where the mouthparts point downward when feeding. Both plant-feeding and predaceous stink bugs can fold their mouthparts backward underneath the body.
Approximately 1 mm in diameter, with small spines around the top that are especially characteristic of the genus Podisus. Eggs are laid 17 to 70... Wikipedia →

Under 5% of wildlife watchers report a Spined Soldier Bug sighting in Toronto on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 867th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Spined Soldier Bug in Toronto on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Spined Soldier Bug is recorded against all the insects logged in Toronto (14 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
